Question

Two systems interacting? What are the inputs and outputs of these systems?

Answer 1

Answer:

Breathing in human on land or during swimming or scuba diving, the human inhales oxygen and exhales carbon dioxide, These carbon dioxide molecules creates "air bubbles" that are then ousted into the water body. The diver at that point draws air from the pressurized air tank, and can inhale or breath. This permits the diver to remain submerged for any longer than only one inhale, and can travel deeper underwater.

Inside this framework, the Oxygen is primary input to the oxygen tanks, which are then utilized by the scuba diver. The diver would draw the oxygen from the tank considered as output in this system.
